We faced this challenge as a team that covered different fields of profesion: Industrial engineers, software engineers, physists and a mechatronic engineer.
We had few knowledge about the tools we could use to do this mobile application, but as we progressed, we were open-minded and ready to learn different skills, so we ended up using the game development tool "Unity 3d" and the graphic design tool "Photoshop CS6", and microsoft's "Powerpoint" for the slides at the presentation of the project.
We had the problem that we didn't have any graphic designer and we were totally new to the toos we used, so we had to learn as we progressed, hence why it was so hard.
